Cam Break in Question

Here's the situation. I getting ready to put my 416 together here in the next few weeks. The cam that's going in requires dual springs. My question is do I need to take the inner spring out during the break in period so I don't run the risk of flattening the cam? I had a buddy of mine go through three .509 purple shafts for that reason. The cam I got is a Comp XE 275 HL (.525 lift 231/237 dur.). I couldn't find anything on Comp's website about running only the outer spring during break in. Have any of you guys ever run a new Comp cam flat during break in because of running both springs?

Thanks
